Composite dental restorations represent a unique class of biomaterials with severe restrictions on biocompatibility, curing behavior, esthetics, and ultimate material properties. These materials are presently limited by shrinkage and polymerization-induced shrinkage stress, limited toughness, the presence of unreacted monomer that remains following the polymerization, and several other factors. Fortunately, these materials have been the focus of a great deal of research in recent years with the goal of improving restoration performance by changing the initiation system, monomers, and fillers and their coupling agents, and by developing novel polymerization strategies. Here, we review the general characteristics of the polymerization reaction and recent approaches that have been taken to improve composite restorative performance.
复合牙科修复体是一类具有独特性能的生物材料，其生物相容性、固化行为、美观性和最终材料性能受到严重限制。这些材料目前受到收缩和聚合诱导收缩应力、有限的韧性、聚合后仍存在的未反应单体以及其他一些因素的限制。幸运的是，近年来这些材料一直是大量研究的焦点，目标是通过改变引发体系、单体和填料及其偶联剂，以及开发新的聚合策略来改善修复体的性能。在这里，我们回顾了聚合反应的一般特征和最近为改善复合修复体性能而采取的方法。
